arm64: hugetlbpage: avoid unused-but-set-parameter warning (gcc-16)

Browse source

[ Upstream commit 729a2e8e9a ]

gcc-16 warns about an instance that older compilers did not:

arch/arm64/mm/hugetlbpage.c: In function 'huge_pte_clear':
arch/arm64/mm/hugetlbpage.c:369:57: error: parameter 'addr' set but not used [-Werror=unused-but-set-parameter=]

The issue here is that __pte_clear() does not actually use its second
argument, but when CONFIG_ARM64_CONTPTE is enabled it still gets
updated.

Replace the macro with an inline function to let the compiler see
the argument getting passed down.
